History
The Duodi Hydropower Station began preparations for construction in 1925, officially started construction in 1927. In 1928, the hydropower station was completed to generate electricity, and Chang Ngopa Rinzin Dorje (强俄巴·仁增多吉) was responsible for production and operation management. At that time, there were only 8 employees in the power station.

The equipment of plant was imported from the United Kingdom by the Gaxag Government in Tibet, with a total installed capacity of 92 kilowatts, mainly for the Gaxag Government, mint and the nobility.

Since 1943, the hydropower station due to the aging of the unit, could not operate normally. In the meantime, Chang Ngopa Rinzin Dorje had applied to the Gaxag Government for the purchase of higher-power generators and accessories, and asked for investment in the expansion of the diversion channel of the plant to increase the power station citation flow, but the government did not give approval.
